Serial No.

To all whom it may concern:

Be it known that I, ABRAM L. CovEY,

Paul, in the county of Howard and State of Nebraska, have invented certain new and useful Improvements in Plows, of which the following is a specification.

The present invention contemplates certain new and useful improvements in plows and relates more particularly to a mold whereby the mold board can be properly adjusted so as to turn the furrow slice in the most effective manner when operating in connection with various types of soils.

To this end the invention resides principally in the provision of a mold board embodying a yielding extension, and novel means for holding the said yielding extension in an adjusted position.

The present case is a divisional application of a case filed August 6th, 1907, Serial No. 387,352.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a plow thereto. Fig. 2 is a detail view of the mold board extension detached together with the braces for holding the same in an adjusted position. Fig. 3 is a similar view showing the opposite side of the mold board extension,

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings the numeral 1 designates the land side of the plow and 2 the handles thereof, the said members being of any approved construction. The mold board comprises in the present instance a lower section 3, and an upper section 4, the rear edge of the latter section inclining upwardly and the lower section 3 projecting beyond the upper section. The mold board extension is m the nature of a yielding or spring stri 5 extending upwardly approximately para lel to the upwardly inclined rear edge of the upper section 4 of the mold board and secured to the rearwardly rojecting portion of the lower section 3 of t 1e mold board. For the purpose of holding the extension 5 in an adjusted position a rod 6 is utilized, one end of the rod being secured to the upper end of the spring extension 5 while the opposite end is secured to some rigid portion of the plow such as the land side 1. This rod 6 is extensible and is formed in two sections having their inner ends oppositely threaded and en gaged by a sleeve 7. \Vith this construction it will be readily a arent that by turning the sleeve 7 the molifboard extension 5 can be drawn inwardly or sprung outwardly and set at the required angle for turning the furrow slice in the most effective manner. A brace member 8 connects an intermediate portion of the rod 6 to the mold board and serves to lock the said rod 6 against bending or vibration. It will be observed that the brace 8 is also extensible and comprises two sections having the inner ends thereof oppositely threaded and received by a sleeve 9 similar to the before mentioned sleeve 7, one end of said brace being formed with an eye by which it may be slipped over the rod 6, after the sections of said rod are disconnected from each other, as indicated in Fig. 3.

Having thus described the invention, what is claimed as new is:

A plow embodying a mold board, an adjustable extension projecting from the mold board, a rod constructed in sections and secured to the mold board extension and to a rigid portion of the plow, respectively, the adjacent ends of said sections being oppositely threaded, a threaded sleeve encircling said ends and adapted to move them towards or away from each other, whereby to extend or contract the rod, and a similarly. constructed brace secured at one end to the mold board and formed at its opposite end with an eye encircling said rod.

In testimony whereof I aflix-my signature in presence of two witnesses.

ABRAM L. COVEY.
